As I watched the President's speech, before the great banner proclaiming "Mission Accomplished," I could not help but be reminded of the tobacco barns of my youth, which served as country road advertising backdrops for the slogans of chewing tobacco purveyors. I am loath to think of an aircraft carrier being used as an advertising backdrop for a presidential political slogan, and yet that is what I saw.

... We expect, nay demand, that our leaders be scrupulous in the truth and faithful to the facts. We do not seek theatrics or hyperbole. We do not require the stage management of our victories. The men and women of the United States military are to be saluted for their valor and sacrifice in Iraq. Their heroics and quiet resolve speak for themselves. The prowess and professionalism of America's military forces do not need to be embellished by the gaudy excesses of a political campaign.
